EMIL BEINER, OF GRATZ, AUSTRIA-HUN GARY, ASSIGNOR TO THE FIRM OF JOI-IAN'N PITCH, ERSTE STEIERMARKISCHE FAHRRAD-FABR-IKS AKTIEN-GESELLSCHAFT,

GRA'IZ, AUSTRIA-HUNGARY.

TYPE-WRITER.

To all "whom it may concern Be it known that I, EMIL REINER, subject of the King of Hungary, residing at Gratz, Austria Hungary, have invented certain new and useful Improvements in Type- W'riters, of which the following is a specification,'reference being had therein to the accompanying drawing.

This invention relates to typewriting machines adapted to use inking ribbons of different colors, and which can also be used for preparing wax stencil sheets, for reproducing apparatus; the arrangement being such that the stroke mechanism of the inking ribbons can be thrown completely out of gear.

The invention consists in an arrangement by means of which this reversal and detachment of gearing of the inking ribbon mechanism, is effected by means of a set of threekeys acting upon only one operating shaft and in such a manner that by depressing one of the keys, the corresponding inking ribbon will be adjusted either for the red or blue color, or wholly moved out of gear.

The accompanying drawing illustrates the invention, whose various features are referred to by both letters and figures.

In the drawing Figure 1, is a side elevation partly in section, of the device. Fig. 2 is a plan view of the same. Fig. 3, is a plan view in detail, of a part of the device. Figs. 4, 5, and 6, show the operating shaft cranks, in three different positions according to a section on the line BB, of Fig. 1, as viewed from the left.

The movement of the ribbon necessary for bringing the red or blue strip into use, 'is effected by the rocking of a shaft t, which, by means of a crank '0 and of a bar 1", actuated thereby, acts upon the operating mechanism in such a manner that when the end of the bar r, (Fig. 2), assumes the positions I and III, the inking ribbon is raised to dif ferent heights, so that in one case the red portion of the ribbon, and in the other case the blue portion thereof, are brought to the typing level, whereas the stroke movement of the inking ribbon is wholly thrown out of gear, and no portion of it is located in front of the types, when the end of the bar 1', is in the position II.

The arrangements by means of which the various positions I, II and III of the bar 1- affect the stroke of the inking ribbon, do not constitute the subject matter of the present Specification of Letters Patent.

application, which relatesonly to those arrangements by means of which the end of the bar is caused to assume the three positions I, II, III, by the said three keys.

On the operating shaft 25, two diametrically opposite cranks, or arms, are keyed: and are engaged from below, by the key levers 3 and 1, respectively, rocking about the axis n, while a third key lever 2 arranged in the center, is forked beyond the axis at and engages the two cranks a, b, at equal distances from the shaft t: by means of suitably arranged springs 2, the keys 1, 2, 3, being movably held at their highest position. The outer keys are preferably colored red and blue, respectively, while the center key is white. I

On depressing the key lever 1 (see Fig. 6), the arm 6 is raised and retained in this position by means of a device hereinafter described, whereby the end of the bar r, as sumes the position I, while at the same time, the key which might have been retained in an operative position, is released and caused to reassume its highest position by the action of its spring 2. In the same way on depressing the key 3 (Fig. 4) the end of the said bar assumes the position III, the previously depressed key being caused to reassume its highest, that is its idle position. On depress ing the central key 2 (Fig. 5,) either of the two cranks 0;, b, which might have been in the depressed position, is raised, and at the same time, the other is depressed until both cranks or arms a, b, are in a horizontal position. In this position of the cranks, the end of the bar a", is in the central position II, in which the ribbon stroke mechanism is thrown wholly out of gear.

In order to retain the key, (1, 2 or 3) which is depressed at any time, and thus also the operating shaft 2,, in the position which it is caused to assume, a resilient plate 7, is positioned at the rear of the key levers 1,2, 3, which bears, in the idle position of the key levers, upon their rear end faces, which are rounded ofi, upwardly. The rear ends of the key levers 1, 2, 3, are depressed which each key lever would be caused to effeet by the cranks a, b, owing to the operation of another key lever, so that the rear ends of the key levers 1, 3, do not contact with the cranks a, b, in their idle positions, but are located lower, by the distance as, (Figs. 1} and 6). On depressing a key, the resilient plate It, is pushed first of all, slightly to the left (Fig. 1) owing to the shape of the rear ends of the key levers and snaps in beneath the operated key lever when the latter has left the plate and has attained its operative position. (See dotted position in Fig. 1.) If another key lever is now depressed, it will push the plate It to the left to that extent, during its idle travel m until the previously locked key is released, so that the latter re-assumes its idle position under the action of its spring a: on the continuation of the movement of the actuated key lever, the latter raises the crank connected therewith, in order to be retained finally, in its own operative position by the plate 72., snappin in beneath it. A second locking of the shai t t in the position it is caused to assume, is effected by the resilient crank arm a, the end of which is formed with a projection d, which in the various positions of the cranks, engages notches is, formed on a rigid cross bar.

Having now described my invention and the manner in which it is used, what I claim and desire to secure is,

1. In a typewriter adapted to use inking ribbons of different colors, an operative rock-shaft suitably journaled, a cross arm carrying a pendent arm on said rock-shaft, a short shaft, a set of keys on saidshort shaft adapted to raise either of said cross arms and said pendent arm, springs on said keys to releasably hold them in their highest positions, a resilient plate at the rear of said keys and bearing against their upwardly rounded off ends, and a projection on said pendent arm to engage notches in a rigid cross bar, for the purpose specified.

2. In a typewriter adapted to use inking ribbons of difierent colors and having a suitably journaled transverse rock-shaft, a cross bar fixed on said rock-shaft, a pendent arm on said bar, a short shaft at a right angle to said rock-shaft, a set of spring controlled keys loose on said short shaft and adapted, when depressed, to raise either end of said cross bar, and a horizontal bar having notches engaged by a tooth on said pendent arm.

3. In a typewriter a device for reversing and throwing out of gear two color inking ribbons comprising an operating rock-shaft, two diametrically opposite arms fixed on said shaft, a key lever acting on each of said arms and a third key lever acting simultaneously upon both of said arms, whereby the operating shaft is rotated into two positions by the operation of said key levers acting in one direction only, and into a central position by the operation ofsaid third key lever.

In witness whereof I have hereunto set my hand in presence of two witnesses.
